HYDROCARBON ACCUMULATION IN ZENGMU PULL-APART BASIN:INSIGHTS FROM THE CONTROL OF TINJAR-WEST BARAM LINE
-
摘要:
南海南部廷贾-西巴兰线断裂是一条规模巨大的北西向走滑断裂,渐新世开始活动,早期具有强烈的右旋走滑特征,晚中新世以来走滑方向变为左旋,更新世至今,走滑方向变为右旋,是曾母盆地与北康盆地、南沙海槽的分界。为了理清廷贾-西巴兰线断裂特征与曾母盆地油气成藏的关系,通过对断裂两侧地震剖面特征、重磁特征、地热流分布特征以及地壳性质和岩石圈厚度的分析,探讨该断裂在曾母盆地形成演化及油气成藏中的控制作用。研究表明:断裂活动为曾母盆地后期的沉积提供了丰富的物源,断裂走滑作用导致曾母盆地具有良好的圈闭,后期的反向走滑使得盆地的沉积中心由南向北迁移;断裂沟通深部热源,有利于油气生成,形成的伴生断层是盆地油气运移的主要通道。
Abstract:The Tinjar-West Baram Line of the Southern South China Sea is a northwest-trending strike-slip fault. As the boundary between the Zengmu Basin and the Beikang Basin and Nansha Trough, the strike-slip fault of the Tinjar-West Baram Line was first activated in Oligocene as a intensely dextral strike-slip fault, then turned to sinistral after late Miocene and, then turned to dextral again since Pleistocene up to present. Based upon the study of seismic profiles, gravity and magnetic data, geothermal heat flux distribution data near the Tinjar-West Baram Line, we studied the crustal nature and lithosphere thickness of the Zengmu Basin, and discussed the control of Tinjar-West Baram Line over the evolution and accumulation of hydrocarbon in the Zengmu Basin. It is concluded that the faulting of the Tinjar-West Baram Line had provided rich source of sediments for the Zengmu Basin. The strike slipping of the faults helped the formation of the good traps in the Zengmu Basin, and the reversed strike slipping in the late period led to the northward motion of the basin depocenters. The faults are important channels to the deep heat source, beneficial to the hydrocarbon generation, and the secondary faults are also the major passages for hydrocarbon migration.
